The 5.3L connecting rods are already as light as they can be. After market will tend to go heavier and stonger.
The 5.3 manifold is already very well flowing. The only way you might be able to improve on it noticeably is go with ridiculously long tube headers optimized for cruise RPM, which means they will end up being like 8 foot long primaries.

Exactly! Unless this is used at low speeds only.
One note about intake flow, unless it's a diesel, your greatest restriction is the throttle. Unless you remove the throttle or at least drive around with it wide open, there's no point in reducing intake restriction and increasing flow. Your best bet is an intake that keeps the fuel atomized, and that's all that really matters.
